Industrial Automation Workers Need a Wider Array of Technical Skills and Knowledge
The complexity of modern automation systems requires partnership and collaboration with an expanded set of industrial and technical disciplines. -
AutoQuiz: Design Specifications for Building Automation Systems
Energy management, access control, lighting control, asset management, communications, life safety, fire alarm, and HVAC controls are all of interest when designing a building automation system -
AutoQuiz: What Is the Continuous Sequence of Steps Performed by a PLC Processor?
The time it takes for the PLC to complete its scanning of all program steps in one operating cycle is called the scan time. -
AutoQuiz: What Network Security Technology Does Not Use Encryption?
A virtual local area network (VLAN) is achieved through configuration of Ethernet switches and not encryption. It divides a physical network into smaller logical networks to increase performance, impr -
AutoQuiz: What Is the Purpose of the Proper Grounding of Electrical Devices?
Proper grounding provides safety, over-current protection, electrical noise reduction, lightning protection, and static electricity reduction. -
AutoQuiz: How to Calculate the Pressure Recovery Factor for Valves
Pressure recovery factor is the increase in fluid static pressure that occurs as fluid moves through a valve from the vena contracta to the valve's outlet and downstream piping. -
AutoQuiz: What Are the Four Key Activities in the Maintenance Cycle of a Control System?
Documentation of the "as left" condition of the control system is a basic requirement for all maintenance, calibration, commissioning, and testing tasks. -
AutoQuiz: What Are Multiple Independent Protection Layers in Relation to Industrial Safety?
A consequence of the concept of multiple independent protection suggests minimization of risk occurs when safety instrumented systems are completely independent from process control systems. -
AutoQuiz: What Is the Response in Level Control System If the Process Liquid Medium Changes?
For a capacitance probe installed in a metal tank, the measured level is proportional to the measured capacitance between the level probe (one capacitor plate) and the tank wall (second capacitor plat -
AutoQuiz: How to Determine Cause of the Apparent Discrepancy in Flow
Periodic visual inspection of orifice plates is required to ensure the integrity of measurement with a digital flow transmitter. -
AutoQuiz: Which Flowmeter Type Does Not Operate on the Principle That a Differential Pressure Is Developed Across a Flow Restriction?
A Coriolis flowmeter develops a flow measurement by measuring the degree of deformation (twisting) of a vibrating tube(s) as the fluid moves through the tube. -
AutoQuiz: What Is an Example of Adaptive Control?
A controller uses a quantitative process model and modifies controller tuning based on how the process responds in relation to the model prediction. -
AutoQuiz: P&ID Determination for Temperature and Pressure Sensors
Instrument technicians often use P&ID diagrams as a reference to identify what type of instrumentation is installed and how the instrumentation is installed in the process. -
AutoQuiz: What is Tree Topology in Fieldbus?
Tree Topology concentrates the connection of several field devices to couplers/junction boxes. Tree topology is also known as "Chickenfoot" or "Star" configuration. -
AutoQuiz: What P&ID Symbol Is Used to Indicate a Temperature Regulator?
The symbol reflects a temperature regulator, filled thermal system. -
AutoQuiz: How to Assess the Optimal Alarm Deadband Setting
Learn to assess the alarm deadband setting on a high alarm. -
AutoQuiz: What Is the Purpose of an Intrinsic Safety Barrier?
An intrinsic safety barrier prevents excess voltage and current from reaching the hazardous area. -
AutoQuiz: How to Assess the Hazard/Risk Category for an Industrial Electrical Panel
Work on energized electrical conductors and circuit parts, including voltage testing on panelboards, or other equipment rated 240V and below would be classified as Hazard/Risk Category 1. -
Book Excerpt + Q&A: New Edition of Guide to the Automation Body of Knowledge
ISA's book is a key resource for preparing for certification, including the ISA Certified Automation Professional, the ISA Certified Control Systems Technician, and the Professional Engineer (P.E.) ex -
AutoQuiz: How is the Reynolds Number Used in Flow Measurement?
For the Reynold's number, the inertial forces in the numerator are given by the product of mass (density), fluid velocity, and pipe diameter.
